Definitions

  • the present invention relates to a method for producing shaped composite materials and using a construction which has at least one first surface section intended for forming the composite material and a second surface section substantially opposite thereto and not provided for forming the composite material, and an intermediate surface section heater.
  • Such composites are in particular fiber-reinforced composite materials, especially carbon- and / or glass-fiber reinforced composite materials.
  • the invention preferably relates to a method using a design for large-area composite materials or components of such composite materials. Large area should be understood here and below as having at least a surface area of 1 m 2 comprising. This includes above all the composite materials and components thereof in the area of the construction of components of wind power plants.
  • Designs for the production of composite materials are the basis for shaping in the field of composite construction, in particular of lightweight construction. They not only ensure a desired geometry but also simultaneously serve for processing the composite materials, in particular for hardening contained therein Matrix.
  • a fiber material is added to the design, which is then impregnated with resin in, for example, a vacuum infusion process and cured by the action of heat.
  • the manufacturing step of the impregnation can also be facilitated by the use of pre-impregnated material (prepreg).
  • a heater is usually arranged in the design which, when operated, can sufficiently heat the composite or the matrix former contained therein to cure ,
  • a heater is usually arranged in the design which, when operated, can sufficiently heat the composite or the matrix former contained therein to cure .
  • heating devices are sometimes provided, which are introduced as heating channels for the guidance of a heating fluid or as resistance heating wires in the design.
  • Such heaters are firmly laminated into the designs comprising glass fiber laminate or carbon fiber laminate and can no longer be removed from the composite of the design or rearranged therein without destroying the composite.
  • the heaters when the heaters are operated, local heat maxima are formed on the surface portions provided for forming the composite, which contribute to uneven heat emission to the composite to be formed and cured.
  • the heat maxima in this case generally correspond to the course of the heating channels or the resistance heating wires.
  • uneven heat release to the composite may result in certain portions of the composite being already hardened or stabilized while other portions have not yet been sufficiently cured or stabilized, i. the quality of the composite material to be produced or the component made therefrom is insufficient.
  • excessive heat input can damage or even destroy the composite material. If too high temperatures occur, local decomposition or destruction of the matrix former can not be ruled out, which of course must be avoided.
  • the prior Technique known in the design of a network of carbon fibers with precisely a suitable heat distribution is from the prior Technique known in the design of a network of carbon fibers with precisely a suitable heat distribution.
  • Such a design is about from the DK 201070038 A known.
  • Carbon fibers have not only a good electrical conductivity but also a satisfactory thermal conductivity, which can ensure a good heat transport, especially in the fiber longitudinal direction.
  • the network of carbon fibers can be formed from a regular network of elongated carbon fibers, which all have a predetermined course direction and are mechanically connected to one another by a suitable arrangement, for example in a fabric, to form a two-dimensional network.
  • a suitable arrangement for example in a fabric
  • the thermal conductivity of the carbon fibers is anisotropic, since the thermal conductivity in the fiber longitudinal direction is appreciably higher than in a direction perpendicular to the course of the fiber longitudinal direction. This sometimes leads to a relatively slow heat distribution for certain geometry shapes with corners and edges, or to different politiciansleitzuen and a non-uniform heat distribution in different directions.
  • the function of the carbon fiber network is not sufficiently suitable for more complex component geometries.
  • a method with a design for the production of molded composite materials or components thereof is proposed, which cost-effective heat distribution of the heat of the heater can allow such that a sufficiently uniform heat distribution over a surface portion results, which for shaping and is provided for dissipating heat to the composite material.
  • a possible isotropic thermal conductivity in the area is to be made possible, which can also allow a sufficiently uniform and rapid heat distribution in complex component geometries.
  • a method with a design is to be proposed, which can be modularly expanded, but without having to modify the heater in their design.
  • the object is achieved by a method for the production of molded composite materials and using a design which at least one provided for forming the composite material first surface portion and this in the
  • the metal structure according to the invention has a length extension or width extension which is greater than the height extent of the metal structure.
  • a flat metal structure does not necessarily consist of flat individual parts, but only the overall geometry of the metal structure has a flat geometry.
  • a metal structure is also flat, if it is areal flat.
  • the second surface section does not have to match the first surface section in terms of its surface area or its geometry. Rather, it is sufficient if a boundary arranged substantially opposite the first surface section is provided as the second surface section. This limitation may also be associated with other components or devices to a more complex structure. The second surface portion also needs to be formed only partially areally.
  • flat metal structures for example in the form of nets, sheet-like foams, films or nonwovens
  • the thermal conductivity of such metal structures is relatively isotropic, ie, the thermal conductivity in a surface direction does not differ from the thermal conductivity in any other direction of expansion.
  • the choice of the metal or the composition and the geometry of the metal structure allows a suitable adjustment of the size of the thermal conductivity itself. This setting can also by the structure of the Metal structure can be supported.
  • flat metal structures are cheaper to produce than about carbon fiber networks.
  • the at least one flat metal structure comprises a metal net and / or metal fleece, in particular a copper net and / or a copper fleece.
  • a metal net can in this case be formed from isolated metal wires which are mechanically connected to one another. Such a connection can be done, for example, by interweaving or interlacing. Likewise, the metal wires can be joined together by soldering.
  • a metal net is characterized in that at least some of the metal wires occupy a predetermined order with each other. This is not the case with a metal nonwoven having a plurality of disordered metal wires.
  • These disordered metal wires in a metal batt may either be relatively short compared to the width and / or length extension of the metal structure, i. less than 5% of these dimensions, preferably less than 2% of these dimensions and more preferably less than 1% of these dimensions, or else have a proportion of relatively longer wires, ie more than 5% of these dimensions.
  • Such metal nets and metal nonwovens are particularly inexpensive, since they can be easily manufactured, and the necessary material costs are relatively low. Copper is particularly well suited for heat conduction, since it may have a thermal conductivity between 350 W / (m ⁇ K) and 400 W / (m ⁇ K). In addition, due to its relative softness, it can be well processed and formed compared to other brittle metals.
  • the at least one flat metal structure is arranged between the first surface section and the heating device.
  • the heat given off by the heater can be transmitted to the first area section particularly effectively and distributed over the area thereof. Due to the relatively low thermal resistance of the metal, therefore, the heat is also transmitted with a particularly low loss and relatively quickly to the first surface section, so that the Heat energy can be efficiently passed on to a composite material to be molded.
  • the at least one flat metal structure is arranged at least in direct contact with the heating device. This ensures a particularly efficient heat transfer from the heater to the metal structure and thus a low overall thermal resistance in the heat conduction from the heater to the first surface portion. In addition, the total heat is distributed more efficiently over the entire area, thus avoiding maximum heat.
  • the at least one flat metal structure is laminated into the design, in particular is laminated over its entire surface.
  • Lamination reduces the inclusion of air bubbles and areas filled with air. However, such have a relatively poor thermal conductivity, i. a relatively large heat resistance, and thus reduce the heat transfer from the heater to the first surface portion of the design.
  • the lamination is typically accompanied by a process step of venting during the lamination, so that after lamination a significantly reduced proportion of air in the design is provided. Due to the lamination, a mechanical stabilization of the metal structure, in particular a metal mesh or a metal fleece can also take place.
  • the at least one flat metal structure has at least regional recesses.
  • such recesses should be relatively small in comparison to the total extent of the first surface section in order not to hinder uniform heat distribution.
  • their dimensions should be sufficiently large to allow about an anchorage in the design.
  • a perforated grid, or a mesh grid made of metal can be laminated in a laminating process in such a way that in the recesses Laminate matrix engages or even penetrates and thus takes a firm anchoring in the design.
  • the recesses are substantially uniform, whereas in the case of a metal fleece, these recesses may be relatively inconsistent. Nevertheless, both types of recesses are suitable for serving as anchors or fixing holes for the metal structure. However, these recesses must not be designed as breakthroughs in their most general form, but can also be designed as recesses or recesses, which can also serve as anchoring structures.
  • the recesses may at least partially be openings that break through the at least one flat metal structure.
  • a particularly secure and stable anchoring of the metal structure in the design is possible.
  • a weight reduction can take place, which can contribute to a significant reduction in the total mass, especially in very large-scale designs, such as in the field of wind turbine construction.
  • Such breakthroughs can also be distributed as well as the recesses in general suitably over the metal structure such that the surface conductance for the heat distribution as well as the anchoring in the design can be adjusted specifically.
  • the at least one flat metal structure has a regular surface structure. This allows a largely uniform heat distribution as well as an industrially inexpensive production of the metal structure. In particular, in less complex designs allows a regular surface structure and a sufficiently uniform anchoring of the metal structure in the design.
  • the at least one flat metal structure at least partially, in particular regularly, distributed over a surface openings. This in turn allows a targeted adjustment of the heat distribution as well as a targeted anchoring of the metal structure in the design.
  • the at least one flat metal structure has a weight per unit area of at least 500 g / m 2 and / or of at most 2000 g / m 2 , preferably 1700 g / m 2 .
  • the basis weights are sufficient to provide suitable heat distribution in conventional designs, but are also sufficiently lightweight not to make the designs excessively heavy. Especially when using metals with a thermal conductivity of more than 500 g / m 2 , these basis weights are well suited to achieve an efficient heat distribution in the design.
  • the at least one flat metal structure is spaced from the boundary surface of the first surface section by at most 25 mm. This ensures a relatively low heat conduction resistance between the metal structure and the first surface portion, in or to which yes the heat energy is to be conducted.
  • a relatively small intermediate layer especially in a laminated construction, which is formed as a glass fiber or carbon fiber or mixed construction, so an unnecessarily high thermal resistance can be avoided. This applies in particular to designs for the construction of wind turbine components.
  • the at least one flat metal structure is configured as a random fiber fleece.
  • Wirrfaservliese are both relatively easy and inexpensive to produce and can also ensure a relatively uniform surface conductivity. Wirrfaservliese are also very good drapable, which is particularly advantageous if the random fiber fleece is introduced or laminated in a design with a more complex geometry.
  • the fiberglass webs may be made of metal wires so that the metal wires are sufficiently thin to cut them in a controlled manner with commercially available cutters.
  • the at least one flat metal structure at least partially has a plurality of layers of metal wires arranged one above the other.
  • layers are typically to be understood as independent mechanically stable structures, which can be connected to each other in any number, or can be placed on each other.
  • the layers are typically produced in isolated fashion in advance and then joined together or placed on top of one another in a further production step. The connection can be made detachable or permanent.
  • the at least one flat metal structure has a thermal conductivity of at least 17 W / (m.K), preferably between 350 W / (m.K) and 400 W / (m.K). K). This typically ensures that the heat resistance to be overcome in a design is sufficiently small in order to make the heat transfer to the first surface section sufficiently efficient.
  • the conductivity value also ensures a sufficiently rapid heat distribution in the design in the course of changes in the thermal profile, i. in the case of local or temporal changes in the heat output by the heating device.
  • the first surface section and / or the second surface section comprises a glass fiber reinforced and / or carbon fiber reinforced composite material.
  • Such composites allow a particularly suitable integration of the flat metal structure in the design by a lamination process.
  • such forms are also suitable for use in the production of large-area composite materials, for example in the field of wind turbines.
  • the design can therefore also be a half-shell for the production of composite components of a rotor blade of wind turbines.
  • the at least one flat metal structure of one of the Design is separable molding is included.
  • the molded part can be detachably removed from the molded part in the sense of separation, in particular reversibly detachably removed.
  • the design can be modular, without having to make further changes to the heating device. Due to the ability of the flat metal structure to achieve a heat distribution even at relatively low temperature differences, the design can also be provided with essays or moldings, in which or on which the flat metal structure is on or applied. In addition, metals also have an advantageous heat capacity, which allows to store the heat transferred.
  • moldings are also suitable for heat distribution, which are not firmly connected to the design, but are arranged with this only in a releasable thermal contact.
  • the molded part is provided for the formation of composite part formations, in particular for the at least partial shaping of gluing tabs of composite components of a rotor blade of wind power plants.
  • the moldings have not only the function of heat distribution but also the shaping. Due to the solvability of the arrangement form-specific settings are possible without further problems.
  • Fig. 1 shows an embodiment of a construction 1 according to the prior art in a schematic sectional side view.
  • the design 1 has a first surface section 10 with a boundary surface 11 facing a composite component (not shown further).
  • the boundary surface 11 is concave and represents approximately the receiving area of a design 1 for the production of a wind turbine blade.

  • a heating device 30 is arranged, which is designed as a heating pipe system for the guidance of a thermal fluid.
  • the heater can also be laminated in the form 1.
  • a second surface portion 20 is provided, which is designed as a boundary surface of a third layer 14 of a fiber composite material is.
  • This third layer 14 of a fiber composite material is in turn slurried or glued to the second layer 13 of a fiber composite material.
  • All three layers 12, 13 and 14 form a stable construction 1, which provides a heater 30 inside.
  • Layers 12, 13 and 14 are typically made as a carbon fiber or glass fiber composite or as a composite composite of both types of fibers.
  • the layers 12, 13 and 14 are also only schematically to understand in the present case, since the individual layers do not differ in their structure and after completion of production of a design 1 can no longer be distinguished.
  • the heating device 30 If the heating device 30 is now operated, first the heating tubes and then the immediate surrounding regions of the second layer 13 of a fiber composite material and the adjacent regions of the third layer 14 of a fiber composite material are heated. Only after appropriate heat conduction the more distant regions of the first layer 12 of a fiber composite material are heated and thus the first surface portion 10th
  • the heat provided in the heating tubes is not sufficiently distributed over the first surface section 10 so that heat maximums or maximum temperatures result on this. These temperature maxima can be found in each case at the locations of the first surface section 10 whose surface regions have the smallest distance to the central points of the cross sections of the heating pipes, which are therefore arranged directly above the heating pipes.
  • the heat output over the first surface portion 10 to the composite material not shown is non-uniform and may contribute to a faulty curing of the composite by namely certain areas are supplied with significantly more heat energy at a higher temperature than other areas. This gives rise to either the areas overheated with heat energy destruction or unwanted changes or other areas that have been relatively underserved with heat energy, are not sufficiently cured.
  • Fig. 2a the design looks in one embodiment Fig. 2a to provide between the first layer 12 and the second layer 13 of fiber composites, a flat metal structure 40, which is constructed here of a number of substructures in cross section. These substructures are about metal strips, which are interconnected.

  • the metal structure 40 is formed flat before it is introduced into the design 1. The introduction takes place, for example, by draping the flat metal structure 40 around the tubes of the heating device 30 and by laminating the second layer with the first layer 12 of a fiber composite material.
  • the metal structure 40 there is a redistribution of heat, so that the heat energy is first distributed over a larger area of the flat metal structure 40 by heat conduction and subsequently introduced into the first layer 12 of a fiber composite material.
  • the surface heat distribution is homogenized, so that the maximum heat or temperature maxima can be largely avoided, or can be significantly reduced in their relative intensity.
